摘要
选用 30 0只 1日龄艾维茵肉鸡 ,随机分为三组 :A组为对照组 ,喂基础日粮 ;B和C组为试验组 ,分别在基础日粮中添加 0 .2和 0 .4mg/kg的烟酸铬。结果表明 :在日粮中添加烟酸铬可以显著地降低肉鸡的腹脂率 (P <0 .0 5 ) ,且有降低皮脂率的趋势 (P >0 .0 5 ) ;同时能提高肉鸡在应激环境中的体重 (P <0 .0 5 )。三组肉鸡的饲料利用率、胸腿肌率、屠宰率及成活率差异均不显著 (P >0 .0 5 )。
one day old AA broilers were randomly divided into three groups: group A was control group, fed on basal diet; group B(basal diet + 0.2 mg/kg organic chromium ) and C(basal diet + 0.4 mg/kg organic chromium ) were treatment groups. The results showed that supplementation of organic chromium to diet reduced the abdominal fat rate (P<0.05) and subcutaneous fat rate (P>0.05); it could increase the broilers' weight in the stress condition, and the effect was significant (P<0.05). There were no significant differences in feed conversion rate, breast thigh meat percentage, slaughter rate and survival rate among the three groups.
